Parasitoids of coccoids were surveyed using malaise traps at the Golcuk Natural Park (Isparta Province), Turkey, in 2009 and 2010. More than 40 species of parasitoids were collected, with twelve being new records for Turkey, of which five, Anagyrus descriptus sp. n., A. alienus sp. n., Aschitus golcukus sp. n., Charitopus bulentyasari sp. n., and Ch. ismailkaraca sp. n. (Hymenoptera: Encyrtidae), are described as new species

New Monoctenus Dahlbom, 1835 (Hymenoptera: Symphyta) species from Georgia

Monoctenus lechkhumensis sp.n. is described from Georgia, Dogurashi and compared to Monoctenus nipponicus Takeuchi, 1940

Sawflies (Hymenoptera: Symphyta) from North Western Georgia (Sakartvelo) (Part II.)

302 specimen belonging to 59 sawflies species were collected in North Western Georgia. Characteristic species are: Monoctenus lechkhumensis Haris & Japoshvili, 2022, Birka catellata (Konow, 1900), Eutomostethus ephippium ssp. vopiscus (Konow, 1899), Strongylogaster caucasica Schaposchnikov, 1885, Macrophya hamata ssp. caucasicola Muche, 1969, Tenthredopsis viridis Zhelochovtsev, 1941 and Calameuta grombczewskii (Jakowlew, 1891). Verticalzontal and zoogeographic distributions of sawflies were analyzed and discussed

Checklist des Aphidiinae (Hymenoptera: Braconidae) et Aphelinus (Hymenoptera: Aphelinidae) de Belgique avec respectivement quatre et trois nouveaux enregistrements d'espèces

peer reviewedAphid parasitoids have good potential for crop protection. However, they have been poorly studied in Belgium, especially in terms of species diversity. Therefore, the aim of this work was to establish the first checklist for the country. To complete the list, aphid parasitoids were sampled in wheat and pea fields near Gembloux (Belgium), in 2013 and 2014. Among the identified species, Aphelinus asychis Walker, Aphelinus daucicola Kurdjumov, Aphelinus fusciscapus (Förster), Aphidius asteris Haliday, Aphidius eadyi Starý, Gonzalez & Hall, Praon barbatum Mackauer, and Trioxys auctus (Haliday) were recorded for the first time in Belgium. Thirty-two Aphidiinae and seven Aphelinus species were included in the checklist. It is hoped this study will stimulate further research, as species diversity is still low compared with neighbouring countries

Opportunities to reduce pollination deficits and address production shortfalls in an important insect pollinated crop

Pollinators face multiple pressures and there is evidence of populations in decline. As demand for insect-pollinated crops increases, crop production is threatened by shortfalls in pollination services. Understanding the extent of current yield deficits due to pollination and identifying opportunities to protect or improve crop yield and quality through pollination management is therefore of international importance. To explore the extent of ‘pollination deficits’, where maximum yield is not being achieved due to insufficient pollination, we use an extensive dataset on a globally important crop, apples. We quantified how these deficits vary between orchards and countries as well as compare ‘pollinator dependence’ across different apple varieties. We found evidence of pollination deficits and in some cases, risks of over-pollination were even apparent where fruit quality could be reduced by too much pollination. In almost all regions studied we found some orchards performing significantly better than others, in terms of avoiding a pollination deficit and crop yield shortfalls due to sub-optimal pollination. This represents an opportunity to improve production through better pollinator and crop management. Our findings also demonstrate that pollinator dependence varies considerably between apple varieties in terms of fruit number and fruit quality. We propose that assessments of pollination service and deficits in crops can be used to quantify supply and demand for pollinators and help target local management to address deficits although crop variety has a strong influence on the role of pollinators

New records of Encyrtidae (Hymenoptera, Chalcidoidea) from Norway V

The study of the family Encyrtidae at the Natural History Museum of Oslo continues. Sixteen species are reported for the first time from Norway in this revision, bringing the total number of Norwegian encyrtids up to 123. Comments on the biology and distribution for these species are given. The three species Bothriothorax cyaneus Nikol’skaya, 1952, Ooencyrtus acastus Trjapitzin, 1967 and Trjapitzinellus arboricola Myartseva, 1980 are reported for the first time from Europe. The aim of this study is to highlight the distribution of the family in Norway and to provide a complete list of the Norwegian species. Posted here with permission from the journal.
